Symptoms of glaucoma

Open angle glaucoma, which is the most frequent type, develops stealthily and without symptoms: visual impairment appears later on and is sometimes accompanied by eye pain or headaches. The visual field diminishes progressively. The central vison becomes smaller. 

 

The tell-tale symptom of advanced glaucoma is visual impairment: firstly the peripheral vision as the centre of the visual field is initially unaffected. If left untreated, this may lead to irreversible visual impairment, even blindness .

 

 

 

• Intra-ocular pressure is measured using a tonometer

• The condition of the optic nerve head and optic fibres is inspected by means of dilated-pupil examination, or by optical coherence tomography (OCT)

• Examination of the angle to be confirmed as open or closed and to see if there is any obstruction to aqueous humour drainage

• Assessment of visual field, which shows the extent of optic nerve lesions and their progression

 

Also, it exists different ways to treat glaucoma.
